Additional Information About Master Spa Temp and Pressure Switches
From sensor cords, temp sensor mounts, and sensor assemblies to switch harnesses and pressure switches, Master Spa Parts offers you a wide range of replacement parts to keep your spa running efficiently.
Temperature sensors need to be replaced if they aren’t seeming to correspond with the temperature they show compared to the feel of the water. Many times, you will see the error code ‘OH’ appear on your main panel. Either the water temperature is 108 degrees, and you should replace the temperature sensor, or, if the water is cool, the sensor is bad and still needs to be replaced.
